Abstract

The afterpolymerization and depolymerization of poly-${\varepsilon}$-caproamide in solid state have been studied under two different reaction conditions, nitrogen flow and sealed state. The degree of polymerization ($\bar{P}$) of nylon 6 increased with the increase in reaction time and temperature, and then reacted finally an equilibrium. In the presence of oxygen, $\bar{P}$ decreased by increasing the reaction time due to the oxidation reaction. Under certain reaction condition, the change of $\bar{P}$ for different initial degree of polymerization ($\bar{P}_0$) tendered toward unity in equilibrium.
